Trouble using variables as the basis of an Iterate.

I’ve build a very basic translation to try and trouble shoot an issue I’m have where I want to use a variable “@listBasis” as the basis for an iteration. I found a good suggestion in a previous post about how you could pass the list and the pointer value ($%l1) as input to the copy statement and then use those values to pull an individual value out of the list and place into an instance of your output field. I appear to be having two issues. The first is that the iterate does not appear to execute for each item in the variable list, and the second is that the value of “$%l1” in my copy statement is returning the name of the variable, and not the index counter. I’ve attached screen shoots below that show my entire setup. Here are the results from the testing tool when attempting to run the translation. NOTE: The first line of the output below was generated from the echo statement in my copy statement to show what was found in xlateInVals.
myList: one two three four five six — pointer @listBasis
MESSAGE 1
Tcl callout error
set myList [lindex $xlateInVals 0]
set pointer [lindex $xlateInVals 1]
echo “myList: $myList — pointer $pointer”
set xlateOutVals]:
errorCode: TCL VALUE INDEX
errorInfo:
bad index “@listBasis”: must be integer?[+-]integer? or end?[+-]integer?
while executing
“lindex $myList $pointer”
invoked from within
“list [lindex $myList $pointer]”
invoked from within
“set xlateOutVals]”
<End of errorInfo>Any input or suggestions would be greatly appreciate.
Thanks,
David

It took a little work, but I did get this to work.
I used an iteration of type “user” with the basis of @listBasis and a variable of %u1. This is where @listBasis was initialized using “=one two three four five six” as found in your example. I did define a separate counter variable @counter and incremented it while in the loop.
I have attached screen shots for you
Input: =one two three four five six
Output:
@listBasis – {one two three four five six}
*** Inside List Iteration ***
List Item: one : List Counter: 1
*** Inside List Iteration ***
List Item: two : List Counter: 2
*** Inside List Iteration ***
List Item: three : List Counter: 3
*** Inside List Iteration ***
List Item: four : List Counter: 4
*** Inside List Iteration ***
List Item: five : List Counter: 5
*** Inside List Iteration ***
List Item: six : List Counter: 6I attached the translation in a text file. I also attached images. I hope this is what you were looking for, but at least you will be able to iterate the list and build upon that.

I ran into the same issue. I had to take my list and used a COPY statement with source @myList –> @myIterationCnt and the used the following code in the pre-proc:
<pre>set dummyList [split [lindex $$xlateInVals 0] ]
set dummyList [llength $dummyList]
set output “”
for {set i 0} {$i < $dummyList} {incr i} {lappend output $i}
set xlateOutVals</pre>
After this my variable @myIterationCnt would contain 5 entries {0 1 2 3 4} if my list had five entries. I could then use @myIterationCnt as the variable in the iterate. This solved the iterate issue, but you then have to pull out the actual value yoyu want from your list. To do that, I have a COPY statement inside the iterate, that has two values on the input. $%u1 and @myList. The target of the copy is my output field, but I have the following code as a pre-proc in the COPY statement:
<pre>set index [lindex $xlateInVals 0]
set drugList [lindex $xlateInVals 1]
set drugList [split $drugList ]
set returnValue [lindex $drugList $index]
set xlateOutVals</pre>
This works because both code blocks in the pre-proc knows to respect the curly braces, while the iterate does not. Hope this helps, sorry I didn’t update the thread when I ran across the issue myself. If you are confused I can try to grab some screen shoots of my setup tonight or tomorrow. -
One other work around besides using a look up table that could work is using a character as a delimiter for a space, example below I used a tick and just string mapped it to the desired space.
@listBasis – {one two three seven<code>with</code>spaces}
echo “List Item: [string map {` ” “} [lindex $xlateInVals 0]] : List Counter: [lindex $xlateInVals 1]”
*** Inside List Iteration ***
List Item: one : List Counter: 1
List Item: two : List Counter: 2
List Item: three : List Counter: 3
List Item: seven with spaces : List Counter: 4Also tried in the basis using a few temp variables for readability.
@listBasis =one two three
@seven = =seven <code>with</code>spaces
basis: @listBasis @seven
bah some of these characters are being stubborn when trying to post.
